Malignant pleural mesothelioma (MPM) is a rare but aggressive malignancy with a poor prognosis. Because of this tumor rarity and overlapping histologic features with other malignancy types, the histopathological findings and diagnostic immunohistochemical workup are essential in establishing the final diagnosis of MPMs. We aimed to review the diagnostic criteria, WHO tumor classification updates, and immunohistochemical staining markers diagnostic value to achieve an appropriate clinical diagnosis.

恶性胸膜间皮瘤的细胞学：诊断标准、WHO 分类更新和免疫组织化学染色标志物的诊断价值

恶性胸膜间皮瘤 (MPM) 是一种罕见但具有侵袭性的恶性肿瘤，预后较差。由于这种肿瘤的罕见性和与其他恶性肿瘤类型重叠的组织学特征，组织病理学发现和诊断性免疫组织化学检查对于建立 MPM 的最终诊断至关重要。我们旨在审查诊断标准、WHO 肿瘤分类更新和免疫组织化学染色标记物的诊断价值，以实现适当的临床诊断。
